The short answer
Choose a firm that works on roofs and timber, rather than insulation alone. Removal needs someone who can read the rafters once the foam is off, repair or replace damaged timber, fix the roof covering and re-insulate correctly. Ask for a survey with photographs first, a written fixed price, a plan for waste disposal and a plan for what goes back in. Avoid anyone who quotes on the phone without looking.
What the job really involves
Spray foam removal sounds simple: scrape it off. In practice the foam is bonded to the rafters, the felt and the underside of the tiles, and taking it off without damaging them takes care. Once it is out, the timber, which has been hidden for years, has to be inspected, and any damp or decayed wood dealt with. The roof covering may need repair, the underlay may need replacing and the loft needs insulating again. It is a sequence of trades in one job: stripping, timber work, roofing and insulation.
That is why the firm matters. An insulation business that knows how to put foam on may not know how to find a leak, judge rot or lay battens. A roofer who has never dealt with foam may underestimate the mess and the dust. You want a team that can do the whole sequence, or manage it in order. Our page on spray foam removal sets out the stages.
What to ask before you hire
Ask whether they will survey first and give you photographs, not just a number on the phone. Ask how they will check the timber behind the foam, and what they do if it is damp. Ask what happens to the foam: where it goes and who carries it. Ask what will be put back, and whether that is priced. Ask how the roof will be protected from rain while it is open. Ask how they handle dust and protect the house. Ask whether the quote is fixed, in writing, and what could change it.
It also pays to ask who will actually do the work. Subcontracting is common, and you should know who will be in your loft. Ask for examples of similar jobs, though not reviews we cannot supply, and ask to see how they document the timber condition. A good firm will welcome these questions.
Warning signs
Be wary of anyone who quotes without looking, who offers a price per square metre with no survey or who insists on payment in advance. Be wary of a firm that is also the company that installed the foam and now says it must come out, or that tells you it must all come out without showing evidence. Be careful of cold callers, a subject covered on our page on spray foam cold calls. Unclear answers on disposal are a red flag: foam is bulky and should be taken away and disposed of properly, not dumped.
Check that the business exists and has a verifiable address, and that you are given something in writing. We make no claim that any scheme or body vouches for us: judge us, as you should anyone, on the survey, the photographs and the written price. Our page on spray foam mis-selling explains how people were misled in the first place, which is a good reason to be careful the second time.
Typical costs and what to expect
Cost guides put removal at £40 to £80 per square metre, though some quote lower, and for a three-bedroom loft £2,000 to £4,500 is a typical UK range. The price depends on area, foam type, access and what the timber needs, so no firm can quote reliably without seeing it. Expect timber repair and re-insulation to be priced separately or clearly included, and ask which.
Compare quotes on the same basis. One firm may price only the stripping, another the stripping plus timber repair and re-insulation, and the cheaper figure can leave out the work that matters. Ask each to list what is included, what is an allowance and what would be extra. A short, clear list beats a long vague one.
Finally, think about timing and access. A good firm will explain how they protect your home, keep the roof watertight while it is open and leave the loft in order. It is reasonable to ask for a start date and an approximate programme in writing, with the understanding that what is found behind the foam can change it.
How we work
We are a roofing contractor first. A free survey comes with photographs of your own roof, a fixed written quote follows, and we repair wherever repair works and say so when the foam can stay. Where work is notifiable we submit the building control application, and the waste leaves with us when the job ends. Details of the work sit on our spray foam page, and you can reach us on 01256 213956 or by WhatsApp.
Every roof is different. A free survey with photos settles it for yours.
